Chapter 8: Statistics
Overview
The RAID controller monitors all incoming commands and calculates various statistics. These statistics are then reported to the controller’s serial interface, where you can view this data. The statistics monitored include: Command Count, Command Alignment, Command Size, Readahead Statistics, Write Clustering Statistics, and RAID 5/50 Write Statistics.
The controller maintains individual access statistics for each LUN and controller port. These can be useful to help balance the load from the host. Identical statistics are maintained for both reads and writes.
